Description

Technical Field

[0001] This utility model relates to the field of veterinary drug packaging equipment technology, and in particular to a high-efficiency packaging and sealing device for soluble veterinary drug powders. Background Technology

[0002] After production, soluble veterinary drug powders are typically packaged using a pre-packaging bag machine. The process involves bag picking, bag transfer, bag clamping, bag opening, filling, sealing, and output. The resulting individual bags weigh between 100g and 1000g each. During bag picking, transfer, clamping, and opening, a first robotic arm picks up a bag from the bag placement chamber. A second robotic arm then transfers the bag from the first arm to two clamping arms, which clamp the bag on both sides. To open the bag, both clamping arms move inwards simultaneously, while two suction cups adhere to both sides of the bag, pulling open the opening. Two support plates extend into the opening to further open the bag. In summary, existing pre-packaging bag machines require multiple complex mechanical structures and numerous steps to open the bag, significantly reducing the efficiency of veterinary drug packaging. Utility Model Content

[0003] This utility model proposes a high-efficiency packaging and sealing device for soluble veterinary drug powders. The bag feeding structure is located below the bag opening chamber, which is compact and shortens the stroke, allowing for quick connection between bag feeding and bag opening, thereby improving the packaging efficiency of soluble veterinary drug powders.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A high-efficiency packaging and sealing device for soluble veterinary drug powder includes a frame, on which a storage compartment and a bag-opening compartment are provided. An ultrasonic sealing assembly is installed inside the bag-opening compartment. A sliding plate is slidably installed inside the bag-opening compartment along the X-axis. The sliding plate is connected to an electric push rod. A proximity switch and a pair of first suction cups are fixedly installed on the sliding plate. A pair of second suction cups, opposite to the first suction cups, are fixedly installed on the inner wall of the bag-opening compartment. The bottom of the bag-opening compartment has a bag outlet and a bag inlet communicating with the storage compartment. A first conveyor belt assembly and several guide rollers are provided at the bag inlet. The first conveyor belt assembly and the several guide rollers are opposite to each other. A second conveyor belt assembly is located below the first conveyor belt assembly. Both the first and second conveyor belt assemblies are located on the side wall of the storage compartment along the Z-axis. A push plate for pushing the packaging bag towards the first conveyor belt assembly is slidably installed inside the storage compartment. A compression spring is provided between the push plate and the storage compartment. A third conveyor belt assembly is located below the bag outlet along the Y-axis.

[0006] As a preferred technical solution, a vertically arranged mounting plate is fixedly installed at the bag outlet. Two guide rollers are hinged to the mounting plate and arranged along the Y-axis. The lower end of the mounting plate is bent away from the first conveyor belt assembly to form a baffle. A conveying channel for one packaging bag to pass through is formed between the first conveyor belt assembly and the guide rollers.

[0007] As a preferred technical solution, the top of the storage compartment is provided with a bag opening, the bottom of the storage compartment is provided with a guide slope, the bottom of the push plate is adapted to the guide slope, an inclined guide rod is fixedly installed on the outer side wall of the push plate, the free end of the guide rod passes through the side wall of the storage compartment and extends to the outside of the storage compartment, and the compression spring is sleeved on the guide rod.

[0008] As a preferred technical solution, the top of the bag opening compartment is open, and a veterinary drug outlet is provided above the bag opening compartment for filling veterinary drug soluble powder after the packaging bag is opened.

[0009] As a preferred technical solution, the first conveyor belt assembly includes a first conveyor belt, the second conveyor belt assembly includes a second conveyor belt, and one side of both the first conveyor belt and the second conveyor belt extends into the storage bin.

[0010] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0011] The high-efficiency packaging and sealing device for soluble veterinary drug powder includes a storage chamber and an opening chamber. Stacks of packaging bags are placed in the storage chamber with their openings facing upwards. Under the action of the push plate and compression spring, the innermost packaging bag abuts against the first and second conveyor belt assemblies. Conveyed by the first and second conveyor belt assemblies, the innermost packaging bag in the storage chamber moves upwards and, after being guided by the guide rollers, enters the opening chamber. The first and second suction cups then begin to work. The first suction cup first adsorbs one side of the packaging bag, and the sliding plate moves towards the second suction cup, which adsorbs the other side of the packaging bag. Then, the sliding plate moves in the opposite direction. Under the adsorption of the first and second suction cups, the two sides of the packaging bag are opened, and the soluble veterinary drug powder is filled into the packaging bag. The ultrasonic sealing assembly seals the packaging bag, and after sealing, the packaging bag falls and is conveyed to the next process by the third conveyor belt assembly.

[0012] In this invention, the bag feeding structure is located below the bag opening compartment, which is compact and shortens the travel distance, allowing for quick connection between bag feeding and bag opening, thus improving the packaging efficiency of soluble veterinary drug powder.

[0013] Because the high-efficiency packaging and sealing device for soluble veterinary powder includes a first conveyor belt, a second conveyor belt, and several guide rollers, the upper end of the innermost packaging bag enters the conveying channel first and is conveyed upwards through the friction of the first and second conveyor belts on the innermost packaging bag, as well as the guidance of the guide rollers. The remaining packaging bags are blocked by the baffles. During the upward conveying process, the lower end of the packaging bag first leaves the second conveyor belt. After leaving the second conveyor belt, it stops working. Then the lower end of the packaging bag leaves the first conveyor belt. After leaving the first conveyor belt, it stops working. At this time, the innermost packaging bag moves into the opening chamber. Under the action of the push plate and the compression spring, the next packaging bag abuts against the first and second conveyor belts, preparing for the next conveying of the packaging bag, thus realizing the conveying of the packaging bags one by one into the opening chamber.

[0014] This invention features a first conveyor belt assembly, a second conveyor belt assembly, and guide rollers, enabling automatic one-to-one conveying of packaging bags. This replaces the two complex robotic arm structures. Through the cooperation of the first suction cup, the second suction cup, and the sliding plate, automatic bag opening is achieved, replacing the two bag clamping arms, suction cups, and bag support plates. This simplifies the complex steps of bag picking, bag transfer, bag clamping, and bag opening in existing bag packaging machines to bag transfer and bag opening, greatly simplifying the mechanical structure and bag opening steps, and improving the packaging efficiency of soluble veterinary powders.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-6 As shown in the figure, the high-efficiency packaging and sealing device for soluble veterinary drug powder includes a frame 1, on which a storage chamber 2 and a bag-opening chamber 3 are provided. An ultrasonic sealing assembly is installed inside the bag-opening chamber 3. A sliding plate 4 is slidably installed inside the bag-opening chamber 3 along the X-axis direction. An electric push rod 5 is connected to the sliding plate 4. A proximity switch 6 and a pair of first suction cups 7 are fixedly installed on the sliding plate 4. A pair of second suction cups 8, opposite to the first suction cups 7, are fixedly installed on the inner wall of the bag-opening chamber 3. The bottom of the bag-opening chamber 3 has a bag outlet 10 and a bag inlet 9 communicating with the storage chamber 2. A second suction cup 8 is provided at the bag inlet 9. A first conveyor belt assembly 11 and several guide rollers 12 are provided. The first conveyor belt assembly 11 and several guide rollers 12 are arranged opposite to each other. A second conveyor belt assembly 13 is arranged below the first conveyor belt assembly 11. The first conveyor belt assembly 11 and the second conveyor belt assembly 13 are both arranged on the side wall of the storage chamber 2 along the Z-axis direction. A push plate 16 for pushing the packaging bag 15 towards the first conveyor belt assembly 11 is slidably installed in the storage chamber 2. A compression spring 17 is arranged between the push plate 16 and the storage chamber 2. A third conveyor belt assembly 37 is arranged below the bag outlet 10 along the Y-axis direction.

[0025] Both the first suction cup 7 and the second suction cup 8 are connected to a vacuum pump via a flexible tube 18. The vacuum pump is not shown in the figure. The weight of a single package of soluble veterinary drug powder is between 100g and 1000g. The vacuum pump creates a negative pressure at the first suction cup 7 and the second suction cup 8 sufficient to adsorb a single package of soluble veterinary drug powder.

[0026] A vertically mounted mounting plate 19 is fixedly installed at the bag outlet 10. Two guide rollers 12 are hinged to the mounting plate 19 and arranged along the Y-axis. The lower end of the mounting plate 19 is bent away from the first conveyor belt assembly 11 to form a baffle 20. A conveying channel 21 for a packaging bag 15 to pass through is formed between the first conveyor belt assembly 11 and the guide rollers 12.

[0027] The arrangement of the conveying channel 21 and the baffle 20, along with the conveying of the first conveyor belt assembly 11 and the second conveyor belt assembly 13, causes the packaging bags 15 in the storage compartment 2 to enter the bag opening compartment 3 one by one.

[0028] The top of the storage compartment 2 is provided with a bag opening 22, and the bottom of the storage compartment 2 is provided with a guide slope 14. The bottom of the push plate 16 is adapted to the guide slope 14. An inclined guide rod 23 is fixedly installed on the outer wall of the push plate 16. The free end of the guide rod 23 passes through the side wall of the storage compartment 2 and extends to the outside of the storage compartment 2. A compression spring 17 is sleeved on the guide rod 23.

[0029] The guide ramp 14 creates a stepped ramp at the top of the stacked packaging bags 15, making the upper part of the inner packaging bag 15 slightly longer and the outer part successively shorter. Compared with the horizontal stacking of the packaging bags 15 at the top, the innermost packaging bag 15 is easier to separate from the other packaging bags 15.

[0030] During the process of placing the packaging bag 15 into the storage chamber 2, the guide rod 23 is pulled outward from the storage chamber 2, the push plate 16 moves away from the first conveyor belt assembly 11, the compression spring 17 is compressed, and the packaging bag 15 is placed into the storage chamber 2 from the bag opening 22. The guide rod 23 is then released, thus completing the placement of the packaging bag 15.

[0031] The top of the bag opening compartment 3 is open, and a veterinary drug outlet 24 is provided above the bag opening compartment 3 for filling veterinary drug soluble powder after the packaging bag 15 is opened.

[0032] The first conveyor belt assembly 11 includes a first conveyor belt 25, and the second conveyor belt assembly 13 includes a second conveyor belt 26. One side of both the first conveyor belt 25 and the second conveyor belt 26 extends into the storage compartment 2.

[0033] The storage compartment 2 includes a vertically arranged end sidewall 27. The end sidewall 27 near the bag inlet 9 is rotatably mounted from top to bottom with a first driving pulley 28, a first driven pulley 29, a second driving pulley 30, and a second driven pulley 31. A first conveyor belt 25 is wound between the first driving pulley 28 and the first driven pulley 29, and a second conveyor belt 26 is wound between the second driving pulley 30 and the second driven pulley 31. A first drive motor and a second drive motor are fixedly mounted on the frame 1. The motor shaft of the first drive motor is connected to the first driving pulley 28, and the motor shaft of the second drive motor is connected to the second driving pulley 30. The first drive motor and the second drive motor are not shown in the figure.

[0034] like Figure 1 and Figure 3 As shown, the sliding plate 4 is vertically arranged, and two pairs of guide columns 32 arranged along the X-axis are fixedly installed in the bag opening compartment 3. The sliding plate 4 is slidably installed on the guide columns 32, and the electric push rod 5 is fixedly installed on the frame 1. The free end of the electric push rod 5 is fixedly connected to the sliding plate 4.

[0035] like Figure 1 and Figure 2 As shown, the third conveyor belt assembly 37 includes a third driving pulley 33 and a third driven pulley 34 rotatably mounted on the frame 1. A third drive motor 35 is fixedly mounted on the frame 1. The motor shaft of the third drive motor 35 is connected to the third driving pulley 33 for transmission. A third conveyor belt 40 is wound between the third driving pulley 33 and the third driven pulley 34. The third conveyor belt 40 is arranged along the Y-axis. Conveying baffles 36 are provided on both sides of the third conveyor belt 40. A guide plate 42 is fixedly installed on the top of each conveying baffle 36. Both guide plates 42 are located below the bag outlet 10.

[0036] Guided by two guide plates 42 and two conveyor baffles 36, the sealed packaging bag 15 falls onto the third conveyor belt 40, which then transports the sealed packaging bag 15 to the next process.

[0037] The ultrasonic sealing assembly includes a first sealing plate 38, a second sealing plate 41, and an ultrasonic generator. The first sealing plate 38 is fixedly installed on the sliding plate 4 and is located between the proximity switch 6 and the first suction cup 7. The first sealing plate 38 is connected to the ultrasonic generator. The second sealing plate 41 is fixedly installed on the inner wall of the bag opening compartment 3 and is arranged opposite to the first sealing plate 38.

[0038] The ultrasonic generator used is the BM2026DX model ultrasonic generator from Dongguan Lanmou Automation Machinery Co., Ltd. The ultrasonic generator is not shown in the diagram. Ultrasonic sealing technology is a technique that uses the principle of ultrasonic vibration to seal two layers of plastic film together through heat sealing or welding. This ultrasonic sealing technology is well known to those skilled in the art and will not be described in detail here.

[0039] like Figure 6 As shown, the control part of this utility model adopts a PLC programmable controller 39.

The proximity switch 6, electric push rod 5, vacuum pump, first drive motor, second drive motor, third drive motor 35 and ultrasonic generator are all electrically connected to the PLC programmable controller 39. The proximity switch 6 is an inductive proximity switch of model LJ12A3 from Wenzhou Dongmenzi Technology Co., Ltd.

[0040] The working process of this utility model patent is as follows:

[0041] Step 1: Under the conveying of the first conveyor belt assembly 11 and the second conveyor belt assembly 13, the innermost packaging bag 15 of the storage bin 2 moves upward and enters the bag opening bin 3 after being guided by the guide roller 12.

[0042] Step two: Proximity switch 6 senses packaging bag 15 and transmits a signal to PLC programmable controller 39. PLC programmable controller 39 transmits a signal to vacuum pump, and first suction cup 7 and second suction cup 8 start working. First suction cup 7 first adsorbs one side of packaging bag 15. Driven by electric push rod 5, sliding plate 4 moves towards second suction cup 8. Second suction cup 8 adsorbs the other side of packaging bag 15. Then sliding plate 4 moves in the opposite direction. Under the adsorption of first suction cup 7 and second suction cup 8, the two sides of packaging bag 15 are opened.

[0043] Step 3: The soluble powder of veterinary drug is filled into the packaging bag 15 from the veterinary drug outlet 24. Driven by the electric push rod 5, the sliding plate 4 continues to move towards the second sealing plate 41. The first sealing plate 38 and the second sealing plate 41 seal the open end of the packaging bag 15.

[0044] Step four: After sealing, the vacuum pump stops working, and the packaging bag 15 falls onto the third conveyor belt 40 after being guided by the guide plate 42 and the conveyor baffle 36. The third conveyor belt 40 then transports the packaging bag 15 to the next process.

[0045] In summary, the bag feeding structure of this utility model is located below the bag opening compartment, which is compact and shortens the travel distance, enabling quick connection between bag feeding and bag opening, and improving the packaging efficiency of soluble veterinary drug powder.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
